使用Spring Boot和Hazelcast实现分布式缓存

import com.hazelcast.core.Hazelcast;
import com.hazelcast.core.HazelcastInstance;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializationContext;
 
@Configuration
@EnableCaching
public class CacheConfig {
 
    @Bean
    public HazelcastInstance hazelcastInstance() {
        return Hazelcast.newHazelcastInstance();
    }
 
    @Bean
    public CacheManager cacheManager(HazelcastInstance hazelcastInstance) {
        return new com.hazelcast.spring.cache.HazelcastCacheManager(hazelcastInstance);
    }
 
    // 如果需要使用Redis作为分布式存储，取消注释以下配置
    //
    // @Bean
    // public RedisCacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
    //     RedisCacheConfiguration cacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
    //             .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));
 
    //     return RedisCacheManager.builder()
    //             .cacheDefaults(cacheConfiguration)
    //             .transactionAware()
    //             .build();
    // }
    //
    // @Bean
    // public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    //     RedisTemplate<Object, Object> template = new RedisTemplate<>();
    //     template.setConnectionFactory(redisConnectionFactory);
    //     return template;
    // }
}

这段代码配置了Spring Boot应用使用Hazelcast作为分布式缓存。HazelcastInstance 被创建并作为
